REGISTER FOR GRAIN-WEIGHING MACHINES, 80C.

SPECIFICATION forming part of Letters Patent No. 339,939, dated April 13,1886.

Application filed October 19, 1885. Serial No. 180,287. (Modeh) To all whom it may concern:

Be it known that 1, CHARLES SEEssLE, of the city of New York, county and State of New Yorlghave invented a new and Improved Registering Apparatus, of which the following specification is a full, clear, and exact description.

This invention relates to an apparatus for registering the number of bushels passing through a grain weighing machine, such as described in Patent No. 317,220, granted to me May 5, 1885. The registering apparatus may, however, also be used in connection with other machinery.

The object of the invention is to produce a registering apparatus which will properly advance an index one number on the revolution of one of the rolls embraced in the apparatus.

The invention consists in the elements of improvement hereinafter more fully pointed out.

In the accompanying drawings,Figure 1 is a front view of myimproved registering apparatus with the faceplate removed. Fig. 2 is a similar view, on a smaller scale,with the faceplate in place. Fig. 3 is an end view of the rolls from the left-hand side, Fig. 1.

The letters a I) represent two cylindrical rolls placed one above the other. The upper roll, a, is rigidly keyed to a screw-spindle, c, that passes loosely through its bearings. At one end the spindle c carries a ratchet-wheel, (I, having ten teeth, and at the other end it carries a hand lever or crank, e, as shown. The ratchet-wheel dis placed in connection with an arm or pawl of the weighing-machine, so that whenever a bushel of grain passes through the machine the ratchet-wheel is rotated to the extent of one tooth; or, in other words, when ten bushels have passed through the machine,'the ratchet-wheel and the roll a will have made one complete revolution. The lower cylinder, 1), is slipped loosely over a fixed shaft, f, and is free to revolve thereon.

g is a hanger, embracing at its upper end the screw -spindle c and at its lower end a tubular extension, 1), of roller I). The hanger g is internally screw-threaded where it embraces spindle c, and thus by revolving such spindle in either direction the hanger moves the roller bin the opposite direction, but without revolving the samethat is to say, the roller I) is moved longitudinally in a direction opposite to the roller a.

his a longitudinal rib projecting radially from the periphery of roller a, and extending from one end of such roller to near the other end, as shown in Fig. 1. This rib h fits into the teeth of a toothed wheel, 4', having ten teeth and keyed to one end of roller 1). It will be seen that the rib h engages the wheel '5, whether the rollers a Z) are directly below one another or not. Around the roller a the figures 0 to 9 are marked in a circle,orin line with each other vertically, and this roller thus constitutes the unit-roller.

Around the roller b the figures 0 O to 100, or to any other figure, are marked in a spiral, ten figures completing each coil of the spiral, and this roller thus constitutes the tens and hundreds roller.

j is a plate that covers the apparatus and has two openings, qr, in line vertically, Fig. 2, through which one figure of each of the rollers is exposed.

As thus far described the apparatus works as follows: By the hand-lever e the spindle c is revolved, and the roller b is by hanger g drawn to the right, and thus the figures shown through the plate j are made to gradually run up or increase. Vhen these figures show the number of bushels to be weighedsay 250the operation is stopped and the ratchet-wheel (Z is made to engage the pawl of a weighingmachine, such as shown in my Patent N 0. 317,220, above referred to. The machine now revolves the spindle aim the op posite direction and runs the register backward until it arrives at 0 011 both rollers, when the weighing operation is completed; but in the revolution of the rollers as thus far described erroneous figures are sometimes made to appear. This is caused by the fact that I make use of two zeros on thelower roller, of which the lower one is used but first, while the upper one is always subsequently used. This construction prevents the rollers from showing consecutive figures during portion of their rotation. To remedy this defect I make use of a tooth or rib on roller (1, in addition to rib h, which advances the roller b only once during its entire travel. This tooth 7c meshes into toothed wheel 5,01 a re-enforcing piece, Z, thereof, Fig. 8, on the first turn of roller a only, and thus revolves the roller 1) to the extent of one figure.

In the drawings the distance between teeth h is is one-fifth of the circumference of roller a, and the tooth 70 thus turns the roller 1) onefifth of a revolution. The register thus construoted will now always properly indicate the number of bushels to be weighed, the figures following in proper consecutive order.

To the lower roller, b, there is affixed a nose, m, to bear against a pin or spring-bolt, n, on

the weighing-machine, and stop such machine when the register shows 0 on both rollers.

I claim as my invention 1. The combination of roller a, having rib h and tooth k, with the roller b,having tooth ed wheel 2', substantially as specified.

2. The combination of roller a, keyed to screw-spindle c and having rib h and tooth is, with the roller 1), loosely mounted on shaft f and carrying toothed wheel 1 substantially as specified.

3. The combination of roller a, having rib 71, tooth k, and acircular numeral scale, with roller b,'having toothed wheel 5 and a spiral numeral scale, substantially as specified.

4. The combination of the following elements: roller a, having rib h and tooth k, with roller 1), spindle c, shaftf, hand-lever e, ratchet-wheel d, hanger g, and toothed wheel i, substantially as and for the purpose specified.

CHARLES SEESSLE.
